Surfaces Ltd specialises in the design and manufacture of off-axis
paraboloids. The company has developed manufacturing techniques over its
40 years history blending modern methods with a high degree of craftsmanship.
With this combination we are able to offer a reliable service tailored to individual
customer needs. Whether the requirement is for custom optics or off the shelf
mirrors, we work to the highest specifications possible.
A cost effective solution
The solution to many problems in optical design may be found by using off-axis
parabolas (OAPs). They can often provide the most cost effective answer
with no compromise in performance. OAP's
offer the advantage of an unobstructed aperture, giving access to the focal
plane in system designs. This ensures pure diffraction patterns on axis with
no spikes caused by "spiders" or other obstructions. This is particularly
important if MTF and similar measurements are being made. Off-axis
parabolic mirrors are especially suitable for broadband and multiple wavelength
applications due to their completely achromatic characteristics.
